Statistical Properties of Long‐Period Plasmapause Surface Waves From Van Allen Probes Observations

Journal of Geophysical Research: Space Physics, 2023
Recent work revealed the existence of plasmapause surface waves (PSWs) with Van Allen Probes observations, which are characterized by the periodic modulations of both magnetic/electric fields and plasma densities, and suggested to be the driver of giant ...

The plasmapause revisited

Journal of Geophysical Research, 1977
Saturation of the dc double probe instrument on Explorer 45 was used to identify the plasmapause. A data base was developed to statistically study the average position of the plasmapause over 14.5 hours of magnetic local time under differing magnetic conditions.

Relationship Between the Locations of the Midlatitude Trough and Plasmapause Using GNSS‐TEC and Arase Satellite Observation Data

Journal of Geophysical Research: Space Physics, 2021
Relationship between the locations of the midlatitude trough minimum in the ionosphere and plasmapause in the inner magnetosphere has been statistically investigated using global navigation satellite system (GNSS)‐total electron content (TEC) and ...

Effects of the Plasmapause on the Radial Propagation of Fast Magnetosonic Waves: An Analytical Approach

Journal of Geophysical Research: Space Physics, 2021
In this study, analytical approximation is used to solve the wave equations near the plasmapause boundary layer in order to examine the validity of ray tracing approach for fast magnetosonic (MS) wave propagations, and then analytical solutions for ...

The Field of Shock‐Generated Alfven Oscillations Near the Plasmapause

Journal of Geophysical Research: Space Physics, 2021
A theoretical interpretation is given for magnetohydrodynamic (MHD) oscillations observed by the GOES and Cluster satellites on November 7, 2004 near the plasmapause (Zong et al., 2009, 2012, https://doi.org/10.1029/2009ja014393, https://doi.org/10.1029 ...

The Relation Between Electron Cyclotron Harmonic Waves and Plasmapause: Case and Statistical Studies

Geophysical Research Letters, 2020
Observationally, electron cyclotron harmonic (ECH) waves are often terminated at the outer boundary of the plasmasphere boundary layer (PBL, i.e., plasmapause). Physics of this empirical relation is not well established.

Prebreakup Arc Intensification due to Short Circuiting of Mesoscale Plasma Flows Over the Plasmapause

Journal of Geophysical Research: Space Physics, 2020
The prebreakup arc at the inner edge of the auroral boundary is intensified upon arrival of an auroral streamer—the ionospheric signature of the earthbound mesoscale plasma flows (MPF).

Evolution of the plasmapause position

Journal of Atmospheric and Solar-Terrestrial Physics, 2001
Abstract The Polar spacecraft, launched in February 1996, has crossed the plasmapause more than 6000 times so that a large number of plasmapause measurements are available at all local time sectors, at low (∼1RE) and high (∼2–4RE) altitudes, and during various magnetic conditions.
